In the newly released trailer, Mimi serves as a Ghost of Christmas Past of sorts, helping YouTube musician Rudy Mancuso sort out his priorities (bro said his phone was the only thing that matters in his life).

Naturally, Carey takes the opportunity to sing her Christmas classic “All I Want For Christmas Is You.”

The ladies of Fifth Harmony will also be joining Carey in the YouTube special. Sadly, after filming their musical cameo, the girl group made a public announcement that original bandmate Camila Cabello is leaving the group on Sunday.

Other stars appearing in the special include DJ Khaled, Boyce Avenue, Ciara, and more. The Keys of Christmas will debut on YouTube Red on Monday.

Carey is certainly enjoying her moment in the spotlight lately. In addition to this festive new role, the pop diva has also been sharing parts of her life with fans in her new reality series, Mariah’s World.
